Atem Switched saying disconnected after programming ESP8266

[RevBryan]

Hi - sorry if this is a daft question. I have built and programmed the ESP8266 for use with my Atem Television Studio HD Switcher (the same one in the diagram on the tally server image on the build page). After I switch on the switcher, then the tally light it still says the switcher status is disconnected if I log in to the tally light web control page.
Am I missing something? the Atem Switcher has an IP and is switched on. It's also plugged into the router!
Any help would be appreciated.

I'd need some more details. Could you send a screenshot,details about your network config, such as switcher IP etc. And maybe logs output from the ESP (you're able to see logs via the web installer)?

Are you sure the switcher is accessible from your WiFi (try connecting from ATEM control software over the same WiFi).
